Understanding the Autism & ADHD Assessment Process
If you are searching for what happens during an autism assessment or ADHD diagnosis, the most important thing to know is that the process is structured, evidence-based, and centred around your child’s individual needs.
At ASD Child Ltd, we follow recognised clinical frameworks such as those outlined by the National Institute for Health and Care Excellence (NICE) to ensure every assessment is accurate, thorough, and meaningful.
Our approach focuses on three key outcomes:
- Clarity about your child’s development
- A recognised diagnosis where appropriate
- Practical guidance for next steps
To explore how this fits into your child’s needs, you can review our full range of neurodevelopmental services.
Our Assessment Process: Step-by-Step
1. Initial Enquiry & Free Consultation
Your journey begins with a conversation.
You can contact us via our contact page or book directly online. During your free telephone consultation, we will:
- Listen to your concerns
- Discuss your child’s behaviours and development
- Explain whether an autism or ADHD assessment may be appropriate
- Outline timelines, fees, and next steps
This step is designed to reduce uncertainty and help you feel informed before committing to an assessment.
2. Pre-Assessment Preparation
Once you decide to move forward, we gather essential background information to build a complete picture of your child’s development.
This may include:
- Parent questionnaires
- Developmental history forms
- School or nursery input where relevant
For ADHD assessments, you may also complete structured tools such as behavioural questionnaires or attention assessments.
This preparation ensures that the assessment is tailored, efficient, and clinically robust.
You can also explore helpful guidance in our resource hub to feel more prepared before your appointment.
3. Clinical Assessment & Observation
This is the core stage of the diagnostic process.
Depending on the type of assessment, this may include:
Autism Assessments:
- Parent interview using structured tools such as ADI-R
- Face-to-face observation using ADOS-2
- Evaluation of communication, behaviour, and social interaction
ADHD Assessments:
- Behavioural screening tools such as CONNERS
- Attention testing such as QBCheck
- Structured clinical interview using tools like Young DIVA
Some elements are completed remotely, while others may involve a single in-person visit.
Our blended approach allows families from across London and beyond to access specialist care without unnecessary travel.
4. Multidisciplinary Review
After the assessment, your child’s case is reviewed by experienced clinicians.
This stage ensures:
- Accuracy in diagnosis
- Consideration of co-occurring conditions
- Alignment with recognised clinical standards
Where appropriate, we may incorporate input from schools or other professionals to provide a well-rounded understanding.
5. Diagnosis & Detailed Report
If diagnostic criteria are met, you will receive a comprehensive written report.
This report includes:
- Clear diagnosis (where applicable)
- Explanation of findings
- Practical recommendations for home and school
- Guidance for EHCP applications
All reports are suitable for use with GPs, schools, and local authorities.
You can learn more about how families benefit from our work by exploring parent experiences and feedback.
6. Feedback Session
We do not simply send a report and leave you to interpret it.
Instead, we provide a dedicated feedback session where we:
- Explain the diagnosis clearly
- Answer your questions
- Help you understand what it means for your child
This is often one of the most valuable stages for parents seeking clarity and reassurance.
7. Post-Diagnosis Support & Next Steps
Diagnosis is not the end of the journey. It is the beginning of understanding.
We offer ongoing support through:
- Psychoeducation sessions
- Guidance on behaviour and emotional regulation
- Support with school communication and SEN planning
- Signposting to trusted services and resources

Benefits of a Structured Assessment Process
Choosing a clear and clinically guided process provides real advantages for both parents and children.
- Removes uncertainty about what happens next
- Provides a recognised and trusted diagnosis
- Enables access to school support and EHCPs
- Helps parents understand behaviour and needs
- Supports long-term development and wellbeing
Why Clarity in the Process Matters
Many families hesitate before booking an assessment because they do not fully understand the journey.
This is completely normal.
Research and performance data show that while more families are visiting ASD Child Ltd, fewer are taking the final step to enquire or book
This highlights a key need:
Clear, transparent information about what to expect.
By outlining the full process, we aim to:
- Reduce anxiety
- Build trust
- Help you make confident decisions
